城市道路用于大排水系统的规划设计方法与案例

Urban roads for major drainage system planning-design methods and cases

近年来,大排水系统在城市内涝防治中的重要作用得到越来越多的认同,作为海绵城市建设的重要内容,我国仍然缺乏大排水系统的具体规划设计方法。进一步梳理了大排水系统的概念、构成及其与海绵城市相关子系统的衔接关系,提出了大排水系统的规划方法与地表径流行泄通道的设计方法,并以某城市片区内涝防治系统构建为例,通过案例介绍了道路径流行泄通道的设计,以期为我国大排水系统的合理构建提供参考。

Abstract： In recent years, the important role o{ major drainage system in urban tlooaing mm- gation have been increasingly recognized. As an important part of sponge city development, the planning and design methods of major drainage system has been lacking. Further combed the de{ini- tion and composition o{ major drainage system, also its relationship with related subsystem of Sponge City, the planning and design methods of major drainage system and overland roadway paths was proposed. On the base o{ the case, the designing of roadway overland {low paths was in- troduced, so as to provide reference to the construction o{ major drainage system in our country.
